Complex Fluids

Complex fluids are materials that exhibit both liquid and solid characteristics, often containing microscopic particles or structures. Examples include ketchup, mayonnaise, and biological fluids like blood. Their behavior can change under different conditions—like being stirred, stretched, or heated. This makes them fascinating to study, as they can demonstrate unique flows, textures, and responses to forces. In soft matter physics, understanding complex fluids helps us learn about fundamental properties of materials that are crucial in everyday products, industrial processes, and biological systems. Their study bridges physics, chemistry, and engineering to innovate and improve various applications.
